1 mole of any substance contains 6.02 x 1023 constituent particles, correct to three significant figures (avogadro constant).
Number of molecules of 4 moles of MgCl2 = 4 x 6.02 x 1023
In every molecule of MgCl2 there are 3 atoms.
Thus, number of atoms in 4 moles of MgCl2 = 3 x 4 x 6.02 x 1023 = 7.22 x 1024

How many atoms are n 4.0 moles of MgCl2?
MgCl2 is an ionic compound with the Mg2+ cation and the Cl- anion in a 1:2 ratio. In each formula unit of MgCl2 there are two Mg2+ and one Cl- ion. So in 4 moles of MgCl2 there will be 12 moles of ions.
How many chloride ions are in sample of salt that contains 2 moles of MgCl2?
Two Chloride ions (2Cl-) ions are needed with their -1 charge on each one to cancel out the +2 charge of the single Magnesium ion (Mg2+). So Magnesium Chloride would have the chemical formula: MgCl2
How many moles of oxygen are in one mole of P4O10?
There are 10 moles of oxygen in one mole of P4O10. This is because each molecule of P4O10 contains 4 phosphorus atoms and 10 oxygen atoms.
How many atoms of hydrogens are in 3 moles of CH4?
There are 12 atoms of hydrogen in 3 moles of CH4. CH4 consists of one carbon atom and four hydrogen atoms. Since each mole of CH4 has 4 hydrogen atoms, 3 moles would have 3 * 4 = 12 hydrogen atoms in total.
How many atoms and are there in 36g of water?
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms

How many moles of phosphorus atoms are there in 8 moles of P4O10?
Since 14 (4+10) moles of P4O10 contains 4 moles of Phosphorus, 8 moles of P4O10 will contain :: (8 x 4)/14 = 2.286 moles of Phosphorus
How many moles of atoms are present in 4 moles of Ca(HCO3)2?
In Ca(HCO3)2, there are 2 moles of carbonate ions (CO3^2-), each containing 3 atoms. So there are 6 atoms in 1 molecule of Ca(HCO3)2. Therefore, in 4 moles of Ca(HCO3)2, there are 4 x 6 = 24 moles of atoms.
How many moles of oxygen gas are needed to make 4 moles of water?
4 moles of oxygen atoms are present in 4 moles of H2O
How many atoms of phosphorus are in 7.6 moles of copper phosphate?
There are 4 phosphorus atoms in one molecule of copper phosphate (Cu3(PO4)2). Therefore, in 7.6 moles of copper phosphate, there would be 7.6 moles x 4 atoms = 30.4 moles of phosphorus atoms.
How many atoms of hydrogen are there in 4 moles of CH4?
There are 24 moles of hydrogen in 4 moles of CH4 because each molecule of CH4 contains 4 hydrogen atoms. Therefore, you have 24 moles x 6.022 x 10^23 atoms/mol = 1.4448 x 10^25 atoms of hydrogen.
How many chloride ions are in sample of salt that contains 2 moles of MgCl2?
Two Chloride ions (2Cl-) ions are needed with their -1 charge on each one to cancel out the +2 charge of the single Magnesium ion (Mg2+). So Magnesium Chloride would have the chemical formula: MgCl2

In the reaction MgCl2 plus 2KOH---MgOH2 plus 2KCl if 3 moles MgCl2 are added to 4 moles 4 KOH what determines how much MgOH2 is made?
Potassium hydroxide is the limiting agent.
How many atoms are in 4.0 moles of sodium?
1 mol has 6,022 140 857.10e23 atoms (The number of Avogadro).4 moles of sodium have 24,088 563 428.10e23 atoms.
In the reaction mgcl2 plus 2koh mgoh2 mgoh2 plus 2kcl if 3 moles mgcl2 are added to 4 moles koh what determined how much mgoh2 is made?
The stoichiometry of the reaction determines the amount of Mg(OH)2 produced. In this case, the balanced equation shows that 1 mole of MgCl2 reacts with 2 moles of KOH to produce 1 mole of Mg(OH)2. Therefore, if 3 moles of MgCl2 are added, 6 moles of KOH are needed to completely react with it and produce 3 moles of Mg(OH)2.
